LOOIVl-SHUTTLE.

Specification of Letters Patent.

Patented Aug. 7, 1906.

tle at the proper time, the incoming fillingcarrier engaging andejecting the previous one from the shuttle, and more particularly theinvention relates to such shuttles used on so-called feeler-looms. Insuch looms the filling change or replenishment is effected automaticallyprior to complete exhaustion of the filling in the running shuttle, sothat the outgoing filling must be parted or cut to fa cilitate thethreading of the new sup El for the shuttle and to prevent the ejectedling being woven into the cloth. Various means have been devised foreffecting such parting of the old filling, and my present invention hasfor its object the production of novel and very effective means forparting such filling.

In accordance with my invention the outgoing filling is severed by orthrough the ej ection of the filling-carrier from the shuttle.

The various novel features of my invention will be fully described inthe subj oined specification, and particularly pointed out in thefollowing claims. Figure 1 is a top plan view of a loom-shuttle providedwith one form of fillin -parting means embodying my invention, tielatter being shown in normal or inoperative position. Fig. 2 is anenlarged transverse section on the line 2 2, Fig. 1, looking toward theright. Fig. 3 is a similar view, but showing the parting means as ocrating to part the filling of the ejected ing-carrier indicated bydotted lines. Fi 4 is an under side view of the right-hand en of theshuttle shown in Fig. l, and Fig. 5 is a perspective view of the movablemember of the parting means detached.

The shuttle-body 1, having a lon itudinal opening 2 extended therethrouh om top to bottom, as hereinishownfifor t ejreception and discharge ofa filling-carrier b, said fillingcarrier having annular projections 12at its butt-end, Fig. 1 to be engaged and frictionally held by holdmg-jaws 3 in one end of the opening 2, and a threading device 4 at theopposite end of the opening, may be and are all of well-knownconstruction.

The threading device is herein shown as of theautomatically-self-threadin type, to thread the shuttle when a fresh filing-carrier is inserted automatically therein-as, for instance, in theNorthrop loom, which forms the subject-matter of United States PatentNo. 529,940, granted to Northrop, and other patents of later date. InFig. 1 the side wall of the shuttle has a feeler-opening 5 for theintermittent entry of the feeler, WhlCh contacts with the filling andindicates the de me of exhaustion thereof, so that filling rep enishmentmay be effected prior to complete exhaustion of the filling.

Referring to Figs. 1, 2, and 3, the shuttlebody is cut out at 6 at theentrance to the threading device to form a guide for the filling t, Fig.1, as it passes to said device from the tip or delivery end of thefilling-carrier. In accordance with my present invention have providedthe shuttle with filling-parting means adjacent such guide portion 6, smmeans in the present embodiment of my invention comprisin a fixed member(shown as two parallel blades 7, fixed in the shuttle- Wood) and amovable cooperating member 8, adapted to swing or rock between them. Theparallel blades 7 are cut out or concaved at their upper edges, as at 9,(see Figs. 2 and 3,) so that the filling maypass freely over the uperedges to'the threadin device, the blades being located in front of t 1etip of the fillingcarrier and transversely to the path of the fillin ThememberS has its inner edge concave as at 10, Figs. 2,3, and 5, and itslower end is bent and extended to form a foot 11, the inner end of thefoot being provided with a cylindrically-bent portion 12, which looselyembraces a headed pivot pin or stud 13, firmly fixed in the shuttle-woodand substantially parallel to the longitudinal axis of the shuttle.

A spring 14 is coiled around the pm and one end is secured to it, itsfree end bearing against the foot 11, as in Fig. 4, the sp being sowound as to normally throw the b ade answmamawvnp- Sinto inoperativeposition, with its tip end 8? withdrawn into a'recess' or housing in theside wall of the shuttle. (See Fig. 2.) When in such normal inoperativeposition, the movable blade is held away from thepath of the circle I)in Fig. 2 indicating the normal relative position of the tip of. thefillingecarr-ier. When the filling is changed or replenished, theincoming filling-carrier strikes the one then in the shuttle and ejectsit from the open bottom of the opening 2 in well-known manner, and asthe ejected filling-carrier is discharged its tip hits the foot 11 andturns it and the blade 8 into the position shown in Fig. 3. The fillingt, Fig. 1, is thus caught between the fixed and movable parting members7- and 8 and cut or parted instantly and cleanly close to the tip of thefilling-carrier and between it and the threading device, leaving averyshort length of the old filling to be pulled out through the threadingdevice and shuttle-eye. The chance of the old filling end fouling ortwisting around theincoming filling is thus practically eliminated, and,further, there is no long end of filling hanging from the tip of theejected filling-carrier. Immediately after the ejected filling-carrierhas passed the foot 11 the spring 14 returns it and the member or blade8 to normal position out of the way of the fresh filling.

So far as I am aware it is broadly new to part the old filling withinthe filling-receiving opening in the shuttle, and I believe it is alsobroadly new to part such old filling by or through the action of theejected filling-carrier. Accordingly my invention is not restricted tothe precise construction and arrangement herein shown, which is merelyone practical embodiment thereof; but various changes or modificationsmay be made by those skilled in the art without departing from thespirit and scope of my invention.

Having fully described my invention, what I claim as new, and desire tosecure by Letters Patent, is

1. A loom-shuttle provided with a threading device and having an openingtherethrough to receive, and permit the discharge of, a filling-carrier,and a' thread-cutting device on the shuttle to cut the filling by orthrough discharge of the filling-carrier from the shuttle.

2. A loom-shuttle having means to engage and sustain -a removablefilling-carrier and permit it to be ejected, and a thread-parting devicecarried by the shuttle and so located as to be operated by the tip ofthe filling-carrier when ejected from the shuttle, to part the fillingnear the tip of such filling-carrier.
